GEORGE E. HUTO-HINS, OF WOROESTER, MASSACHUSETTS, ASSIGNOR TO THEOROMPTON & KNOWLES LOOM WORKS, OF SAME PLACE.

LOOM.

SPECIFICATION forming part of Letters Patent No. 606,553, dated June 28,1898 Application filed January 10,1898. 7 Serial No. 666,148. (Nomodel.)

To all whom it may concern.-

Be it known that I, GEORGE F, HUToHINs, a citizen of the United States,residing at WVorcester, in, the county of Worcester and State ofMassachusetts, have invented certain new and usefullmprovements inLooms,

v of which the following is a specification.

My invention relates to looms, and more particularly to a supplementalmechanism to be applied to and used upon wide looms for. weaving thickor heavy fabrics, such as duck! cloth, &c., to prevent any bending orback spring of the layintermediate its connections with the crank-shaftwhen the lay is in its forward position. V

The object of my invention is to provide a simple and effectivemechanism adapted to be applied to and combined with looms of ordinaryconstruction of the class'above re: ferred to and forthe purpose abovestated; and my invention consistsin certain novel features ofconstruction of my mechanism, as will be hereinafter fully described.

Referring to the drawings, Figure 1 is a rear perspective view ofportions of a loom with my improvements applied thereto; and Fig. 2 is aplan view, on an enlarged scale, of my supplemental mechanism shown inFig. 1.

In the accompanying drawings, 1 is a loom side or end. '2 is a loomcenter. 3 is the driver-shaft, and 3 the driving-pinion. 4 is the bottomshaft 4; is the crank-shaft. 5 and 6 are intermediate gears. 7 is thecrankconnector. 8 is the lay; 9, one of the layswords, secured at itslower end on the rockershaft 10. 11 is the hand-rail, and 12 a portionof the reed. All of the foregoing parts may be of the ordinary and usualconstruction.

I will now describe my supplemental mechanism.

On the bottom shaft 4L is fast a gear 13, which meshes with a gear 14:,fast on a short shaft 15, journaledin bearings 16 on the crossgirth 17and loomcenter 2. (See Fig. 2.) On the end of the shaft 15 is fast acrank disk or wheel 18, and on the pin or stud 19 there is looselymounted a roll 20. A lay-sword 21, located intermediate the endlay-swords 9, is secured at its upper end to the rear portion of the lay8 and secured at its lower end on removable and adjustable by bolts 23or otherwise.

The cam -surface 22 is so arranged relathe rocker-shaft 10 and has acurved or cam surface 22 thereon, which is preferably made tively to theroll 20 on the crank-disk19 and the revolution of said disk is so timedthat when the lay is very near its forward position on its forwardstroke the roll 20 will be j and bring it into alinement when the lay isat its extreme forward movement, thus beating up the cloth in'a straightline the full length of the lay.

In the ordinary Weavin g of the loom, in case there is no back spring ofthe lay, the roll 20 .may be carried around with the disk 18 and pass bythe cam-surface 22 on the stand 21 on the forward stroke of the laywithout any engagement therewith.

By the construction of my mechanism it will be seen that the roll 20 isin position to engage the cam-surface 22 on the stand 21 only during aportion of a'revolution of the disk 18, and during the rest of therevolution of said disk there is no engagementm possibility-ofengagement between the roll 20 and cam-surface 22. Thisis an advantage,as it reduces Very much the friction on the parts and any loss of power.

I have shown in the drawings only one center lay-sword 21 and one crankdisk or wheel 18 and engaging roll 20; but it will be understood thatthere can be one or more on the 100111, according to the width of the100m.

It will be understood that the details of construction of some of theparts of my improvements may be varied, if desired. For example, acrank-arm carrying the roll 20 may be used in place of the disk or wheel18, as indicated by dotted lines 21, Fig. 1. The roll 20 may bedispensed with and only a stud or pin used.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In aloom, the combination with the lay,

and means for actuating the same, and a laysWord intermediate the endlay-swords, having a curved or cam surface thereon, to be engaged by aroll or pin on a crank disk or arm, of said crank disk or arm carrying aroll or pin to engage said curved or cam surface during a portion onlyof the revolution of said crank, and means for supporting and revolvingsaid crank, substantially as shown and described.

2. In a loom, the combination with the lay, and means for actuating thesame, and a laysword intermediate the end lay-swords, havporting andrevolving said crank, substan- 2o tially as shown and described.
